听闻英语的最佳学习时间在小学,可是有些同学在小学的时候不好好学习,导致在九年级的时候学英语学的很吃力。于是他们问九年级英语的知识点有哪些呢?下面是由出国留学网小编为大家整理的“九年级英语知识点归纳总结 ”,仅供参考,欢迎大家阅读。
九年级英语知识点归纳总结
重点语法
一般现在时的被动语态
一. 概念理解
1. 时态:在英语语言中,时态主要讨论行为动词发生的时间。
如:He often helps me with my English. 他经常帮助我学英语。(help这个动作经常发生often;故用一般现在时)
2. 语态:在英语语言中,语态主要讨论句子主语与行为动词的关系。语态有两种:主动语态和被动语态。
① 主语是动作的发出者(执行者)为主动语态。
如:The tall boy often hits his classmates (主语boy是谓语动词hit的发出者)。
② 主语是动作的接受者(承受者)为被动语态。汉语中常用“被”、“给”、“由”、“受”等词用来表示被动,而英语用:助动词be + 及物动词的过去分词构成
如:Chinese is spoken by the most people in the world(主语Chinese是谓语动词speak的承受者)。
3. 语态与时态的关系:在任何一个英语句子中都同时存在语态和时态,他们是分析一个英语句子的两个主要元素。
如:① He is looking after his sister at home. (此句为现在进行时的主动语态结构)
② He is being looked after well by his parents. (此句为现在进行时的被动语态结构)
二. 被动语态最基本的句型结构:be +及物动词过去分词
说明:① be 有时态,人称和数的变化。
② 被动语态中的谓语动词必须是及物动词;因为被动句中的主语是动作的承受者,某些短语动词如look after, think of, take care of, work out, laugh at等,也可用于被动语态。
三. 被动语态的使用
1. 当不知道或没有必要指出动作的执行者时,常用被动语态,这时往往不用by 短语。
Mr. White, the cup with mixture was broken after class. (只是告诉老师杯子坏了,不知是谁弄坏的,或不想说出谁弄坏的)。
2. 突出或强调动作的承受者,如果需要说出动作的执行者,用by 短语。
如:The cup was broken by Paul.
四. 主动语态变被动语态的变法:主动语态与被动语态之间如何转换
1. 把主动语态的宾语变成被动语态的主语。
2. 把主动语态的谓语变成被动语态的be + 过去分词,时态要与原句保持一致。
3. 把主动语态的主语变为介词by的宾语,放在被动语态里谓语动词之后,by 短语可以省略。如果原句主语是地点名词,在被动语态中用in + 地点名词作状语。
五. 一般现在时的被动语态:am /is/ are +done
如:Tea is grown in Hangzhou. 杭州种植茶叶。
